Application July 18, 1947, Serial No. 761,806

3 Claims. 1

This invention relates to new and useful improvements in lamp shades and the primary object of the present invention is to provide a lamp shade so designed as to permit the same to be handled or contacted without injury to the person engaging the same when the bulb encased by the shade is energized.

Another important object of the present invention is to provide a reflector including novel and improved cover means therefor which is quickly and readily removed from the reflector to permit cleaning of the cover or the reflector.

A further object of the present invention is the provision of a shade for the foregoing purposes and one that is applicable to any type of light in a simple manner without the need of tools therefor.

A'still further aim of the present invention is to provide a lamp shade that is simple and practical in construction, strong and durable in use, relatively inexpensive to manufacture, and

otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure 1 is a top plan view of the present shade;

Figure 2 is a bottom plan view showing the device encasing a light bulb;

Figure 3 is a side elevational view of Figure 1;

Figure 4 is a transverse vertical sectional view taken substantially on the plane of the section line 4-4 of Figure 2; and,

Figure 5 is an enlarged longitudinal vertical sectional view taken substantially on the plane of the section line 5-5 of Figure 2.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed av preferred embodiment of the ,present invention, the numeral l represents a substantially bulb-shaped covering or casing of heat insulating material having a plurality of radial or criss-cross depressions l2 formed or pressed therein during the shaping or forming of. the cover.

Extending between adjacent depressions and defined by the depressions, are air chambers l4.

Suitably secured to the outer surface of the cover [0 and extending transversely about the cover are spaced parallel channel shaped shells iii of suitable heat insulating material.

The numeral 18 represents a substantially bulbshaped inner lining or reflector of such material to reflect the light rays of bulb 20 in a definite pattern.

The outer extremity of lining I 8 is rolled outwardly upon itself to provide a sleeve 22, that terminates outwardly from the outer extremities of cover I'll.

The sleeve 22 and the outer extremities of the cover are retained in position to each other by a plurality of substantially U-shaped spring clips 24, having one of their ends secured to the reflector.

A plurality of air vents or apertures 26 are provided in the shells at selected points to permit additional air ventilation into the shells other than at their open outer ends.

In practical use of the device, the rear edge of the lining is suitably secured to or forms an integral part of a retaining ring or base 28 that is suitably secured to the socket 38 supporting the light bulb, by any suitable means.

The bulb being energized will heat the reflector and the heat radiated from the reflector will rise in chambers H, but as the shells project outwardly from the periphery of the cover it will be almost impossible for a person to contact the heated portion of the cover, and further air enters through apertures 26 into the shells l6 and tends to cool the entire cover.

In View of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled inthis art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a prefered embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

I 1. A lamp shade comprising a cover of heat insulating material, said cover having externally criss-crossed hollow ribs providing air chambers within said cover, air vents provided in said chambers, an inner lining for said cover, and means for securing said inner lining to said cover.

2. A lamp shade comprising a cover of heat insulating material, said cover having externally criss-crossed hollow ribs providing air chambers 2,455,994 3 4 within said cover, air vents provided in said cham- REFERENCES CITED bers, an inner lining for said cover, means for securing said lining to said cover, and substang ai g ggfi gg are of record in the tially channel shaped shells carried by the outer surface of said cover and extending transversely 5 UNITED S ATES PATENTS about said cover.
